P360 joystick maintenance?

Well, a couple of months ago I bought a MAS with p360 and it worked without a hitch until recently where the stick would start to feel sluggish and would tend to stick to a certain side. The “sticking” was noticeable with other people using my MAS.

So I opened it up and reached the spring where I put in some petroleum jelly at the ends of each spring and closed it. Now it moves smoothly except you get to feel a “click” every now and then. My guess is that the spring ends slip in and out of some depressions inside the assembly. The stick feels fine but the clicking detracts from my concentration and I would like to know if anybody here has had a similar problem. A fix would be appreciated :wonder:. Thanks in advance.
